Patented Mar. 19,1912.

To all whom it may concern: I Be it known that I, EDWARD G. Bonn, acitizen of the United States, residing in the city of Philadelphia andcounty of Philadelphia, State of Pennsylvania, have invented certain newand useful Improvements in Metallic Doors, of which the following is aspecification.

This invention relates to metallic doors constructed largely ofsheet-metal and has reference more particularly to the locking devicesemployed with such doors. The invention is specially applicable to doorshaving rails formed of strips of sheet-metal bent on lines extendinglengthwise thereof to the desired cross-sectional shape, these railsbeing secured together at their ends to form a frame and panels ofsheet-metal being secured thereto within the frame.

The invention concerns the combining of the locking devices with a doorof this type and involves the provision of an improved constructionwhereby great strength and good wearing qualities are secured in astructure which may be manufactured conveniently and at comparativelylow cost.

I have illustrated the preferred embodiment of the invention in theaccompanying drawings, in which- Figure 1 is an elevation of a portionof a metallic door; Fig. 2 is a side view of the same; Fig. 3 is a viewcorresponding to Fig. 1, one side-plate of the locks being removed; Fig.4 is a view corresponding to Fig. 1, the locks bein removed; Figs. 5 and6 are plan views of t e two locks; Fig. 7 is a side view of thestructure shown in Fig. 4; and Fig. 8

- is a transverse section on line 8- 8 of Fig. 3.

Referring to thesedrawings, the door shown is of the type made ofsheet-metal parts, these including rails 1 secured together at theirends to form a frame, and panels 2 secured to these rails within theopenings of the frame. Each of the rails 1 preferably consists of asingle strip of sheetmetal bent along lines'extending lengthwise thereofto the desired cross-sectional configuration, Preferably these rails areof rectangulait'cross-section, and each is provided with a flangeprojecting from the inner edge thereof to provide means for se-' curlngthe panel to the rail.

outer edge provided with a lengthwise projection or bead 3. In order toprovide means for securing the locking devices to the door and distriuting the strains thrown 'thereon to the parts of the door, a metallic-lines in Fig. 4, during the process of constructing the door.Preferably the strip for the rail 1 is partially foymechthe casting 4-is then inserted therein, and the formation of the rail 1 is thencompleted; thereafter the casting 1. may, if desired, be secured to therail 1 by welding these parts together.

In the edge of the rail 1, an opening is cut ofa size corresponding tothat of the frontplate of the look. This opening is shown at 5 in Figs.at and 7. The portion of the looking devices which fits within the railof the door is made'in two parts, these parts being shown in Figs. 5 and6. These two parts may be considered as two distinct locks and may betermed for convenience the latchlock and the key-lock. The part 6, shownin Fig. 6, is provided with a ront-plate 7 of the same size as theopening 5 in the ed e of the rail 1, so that the front-plate will %tsnugly in this open'ng. The portion of the part 6 -in rear of tllisfront-plate is of the same height or of less height than the front- Therail for r the outeredge of the door may have its of the door. The part10 is also constructed of such a size that it may be inserted within thedoor through the opening 5. This par't 10 is provided with akey-actuated locking member 11. moved back and forth by means of a keyinserted in the keyhole 12. The sides of the rail 1 are provided withsuch openings as may be required for the secur ing devices employed insecuring the parts of the locks in position, and for those memhere whichmust coact with the parts of the locks from the exterior of the door,but none of these openings is of such size as would materially weakenthe door structure. Thus,

an opening is provided, as shown at 13 in in assembling the parts upon adoor, the.

hey-lock i is first inserted t rough the opening and then moved upwardlywithin the frame or casting r to approximately its proper position. Thelatch locit ti is tien inserted through the opening 5 and movedbackwardly therein until the irontplate Y of this part fits within theopening" 5, its outer surface being flush with the edge of the door. Twoside-plates 16 and l? are then positioned, one on eitlier si ie of therail 1, these being of the construct-ion commonly employed in looks ofthis character, such as are used on the doors of railr-Jay handle on oneof the side-plates is provided with. a lock-operating rod 18, square incross-section, which passes through the openings in the sides of therail. 1 and the opening in :he operating member 9, its opposite endentering squared opening in the handle on the other side-plate lhus byturning either of the handles on the side-plates, the member 9 may beturned and the outwardiy projecting end oi? the locking member 8 raisedso as to permit of opening the door. The upper movable ends of thehandles on the side-plates have a rod 1%) connecting them and extendingthrough the opening 13, this rod being adapted to move in the path ofthe locking member 11 when that member is retracted.

In order to support the locks 6 and 10 rigidly in their positions;projecting pins may be provided on the side-plates 16 and 17 enteringopenings in the looks, or open-' ings may be provided for screws usedfor this purpose. In the present instance, I have shown openings 20adapted to receive pins 2% projecting inwardly from one of theside-plates and entering openings 21 in the key-loclr 10. Also, openings22 are provided in the sides 01'": the rail 1, to receive screws 23, theinner ends of which coact with the opposite side-plate so asto draw thetwo side-plates together tightly upon the sides of the rail 1, and thesescrews 23 may, it de sired, be arranged to hol.dthe two locks in lace.

It will be seen that in the construction illustrated the rail of thedoor is not weakened weaves? ing-devices combined in a single structure.instead, locking-devices are employed consisting of two separate locus,a key-lock and a latch-lock, which may be inserted in the rail of thedoor, one independently of the other, and which, when within the rail,are held in proper relative positions so that they will coact in thedesired manner. To position the locks within the rail of the door, it isonly necessary that there be provided'in the edge of the door an openingof sufiicient size to permit the insertion of the two locks edgewisetherethrough successively. After the key-loch has been moved through theopening, it is moved in the direction of the length of the rail and awayfromthe opening and the latch-lock is then inserted.

WVhen the latch-lock is in position its front plate closes the openingin the edge of the rail. The two locks are held in proper relativepositions by projections on the side plates lying on opposite sides ofthe rail. The use of a frame for the locks, such as that shown at i, isnot necessary, but its use is preferred; when such "frame is used, it isoi such shapethat it will not interfere with the free movement of thekey-lock 10 in the direction of tee length of the rail when theprojections on the side plates have been withdrawn from the openings inthe; keylock.

Having now described my invention, what i claim as new therein anddesire to secure by Letters Patent is as follows l. The combination of adoor which is hollow adjacent to one edge thereof and which has anopening in said edge, a lockpart movable through said opening andmovable within the door away from said opening, a second lock-partmovable through said opening and means for holding sald lock parts inposition within the door with said second lock-part closing the saidopen ingthrough the edge of the door, substantially as set forth.

2. The combination of a door consisting of hollow sheet-metal rails andpanels secured thereto, one of said rails having an opening in the edgethereof, a key-lock movable through said opening and movable within therail in the direction of the length of the rail and away from saidopening, a latchlock movable through said opening and means for securingsaid locks in position within the rail with said latch-lock] closing thesaid opening in the edge of the rail, substantially as set forth.

3. The combination of a door havingna hollow sheet-metal rail at oneedge thereof and an opening in the edge of the rail, a frame securedwithin the rail adjacent to said opening, a lock movable through saidopening and movablewithin the rail and frame in the direction of thelength of the rail and away from said opening, a second lock movablethrough said opening and means for securing said locks in positionwithin said frame with said second lock closing the opening in thetedgeof the door, said first lock, when released by said securing means,being capable of movement into congact with the second lock,substantially as set brth.

This specification signed and witnessed this 23rd day of July, 1910.
